Um, we weren't kidding when we said you should cash in your bonds, because if you wanna buy Barry Bonds's mansion, you'll need every penny!!

That's right, he's putting up his Beverly Hills home for $25 million!

It has 17,100 square-feet, 7 bedrooms and 14 bathrooms. It's in the same exclusive gated community where Real Housewives of Beverly Hills stars Adrienne Maloof and Lisa Vanderpump used to live!

Plus you can't forget the music room, theater, trophy display room, wine room, gym, spa, elevator, guest house and the pool on the 1.85-acre property.

Here's what the real estate company says:

“Extraordinary luxury living with the utmost in privacy, this grand scale, yet elegant, Italian villa estate, serves equally to entertain heads of state, host charitable events or just be at home with family. Once within the property’s gates, you are transported to another world; one of serenity and privacy and away from the hustle bustle of the city which lies just minutes below.”

So how much did he originally buy it for?

Only $8.7 million! He did a LOT of renovations, including a two-story wing to the home, expanding its square footage.
